摘　　要：针对目前有关授权中存在的一些问题,如:一次授权,终身有效;授权控制深度不够等特点.文中给出了一种分布式系统下的多级授权管理模型.该模型采用基于信任度的方式进行授权并且定期对各个实体的可信性进行验证,对不符合条件的实体可以及时处理,并且对各个实体的授权均要与授权源及一些相关实体通信,加强了授权的控制.Authorization is a part of trust management,the existing systems have some faults as follows： one is ＂one time authorization,effective for ever＂,the other is authorization depth is not controlled effectively. To address the problems,this paper proposes a multi-level authorization management model in distributed system. This model uses a way based on the trustworthiness to authorize and inspect every entity regularly. To the entities that does not conform the condition,they will be took out. Moreover,the correspondence among the entities is controlled by the authorization root,strengthen the depth control.
